Queensland's Resources Council is warning of more job losses in the coal industry, with mining companies continuing to close mines and postpone projects to save money.

The Resources Council's executive director Michael Roche has told Radio National mining firms feel things are even worse now than they were during the global financial crisis.

"It is a perfect storm because at the time of the GFC costs weren't as high," he said.

"So costs have got out of control in the industry, and then we've had the added burden of an Aussie dollar stubbornly well above parity, and then governments come along from 1 July with the carbon tax, and then from 1 October in Queensland, higher royalties."
